Product details
Overview
STM32G071RBI6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in LQFP64 package, operating up to 64 MHz with 128 KB Flash and 36 KB SRAM. It integrates dual 12-bit DACs, 12-bit ADC (0.4 µs conversion), four USARTs (including ISO7816/LIN/IrDA support), USB Type-C™ Power Delivery controller, and RTC with alarm/wakeup-enabling compact, low-power industrial control and smart sensor node designs.
For engineers reviewing the STM32G071RBI6 datasheet, STM32G071RBI6 pinout, STM32G071RBI6 application, or STM32G071RBI6 equivalent, key selection criteria include its 64 MHz Cortex-M0+ core, 128 KB securable Flash with ROP protection, dual DAC + 16-channel ADC capability, USB-C PD controller integration, and support for -40°C to 125°C extended temperature operation.
Technical Context
The STM32G071RBI6 implements an Arm Cortex-M0+ core with Memory Protection Unit (MPU), supporting TrustZone-like secure boot via Readout Protection (ROP) Level 2 and securable Flash area. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and ±1% internal 16 MHz HSI with PLL-enabling precise timing across mixed-signal applications.
Peripheral interconnect uses a flexible AHB/APB matrix with 7-channel DMA and DMAMUX routing. Analog subsystem includes two rail-to-rail comparators with programmable hysteresis, VREFBUF for DAC/ADC reference stabilization, and hardware oversampling (up to 16-bit effective resolution) on the 12-bit ADC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G081RBT6 | Same package and pinout; adds 1x additional USART and 1x additional SPI; identical Flash/SRAM and peripheral set otherwise. | Required when design needs 5 total USARTs (e.g., dual RS-485 + BLE UART + debug + ISO7816). | Select if extra serial interface bandwidth is needed without changing PCB layout. |
| STM32F072RBT6 | Legacy Cortex-M0 (not M0+); no USB-C PD controller; 16 KB more SRAM but same 128 KB Flash; lacks VREFBUF and hardware oversampling. | Suitable only for cost-sensitive legacy designs where USB-C PD and high-resolution ADC are not required. | Choose only for migration from existing F072-based platforms; avoid for new USB-C or precision analog designs. |
Compared with STM32G071RBI6, the G081 offers expanded serial connectivity without layout change, while the F072 trades modern features (USB-C PD, VREFBUF, oversampling) for marginal SRAM gain-making the G071 optimal for USB-C–enabled, analog-intensive edge nodes.

FAQ
What is the maximum operating frequency and voltage range of the STM32G071RBI6?
The STM32G071RBI6 operates at up to 64 MHz using its Arm Cortex-M0+ core and supports a supply voltage range of 1.7 V to 3.6 V. Its internal 16 MHz RC oscillator has ±1% accuracy with PLL, enabling precise clock generation without external crystals in many applications. The device maintains full functionality across its entire voltage and temperature range (-40°C to +125°C).
Does the STM32G071RBI6 support hardware cryptographic acceleration?
No, the STM32G071RBI6 does not include dedicated hardware cryptographic accelerators (e.g., AES, SHA, PKA). Security relies on software libraries and its memory protection unit (MPU), Readout Protection (ROP) Level 2, and securable Flash area. For hardware crypto, ST recommends the STM32G0B1 or STM32L5 series, which integrate AES-128 and PKA engines.
Can the USB-C Power Delivery controller operate independently of the main CPU?
Yes-the USB-C PD controller includes autonomous state machines for CC line monitoring, voltage negotiation, and fault handling. It can wake the Cortex-M0+ core from Stop/Standby modes via dedicated interrupts and maintain basic PD communication even when the CPU is halted, enabling always-on port negotiation without continuous CPU load.
What are the key differences between the STM32G071RBI6 and STM32G031K8T6?
The STM32G071RBI6 (LQFP64, 128 KB Flash, 36 KB SRAM) offers double the Flash and SRAM of the G031K8T6 (UFQFPN32, 64 KB Flash, 16 KB SRAM), plus two additional USARTs, USB-C PD controller, VREFBUF, and hardware oversampling. The G031 targets ultra-compact, cost-optimized designs; the G071 serves complex, feature-rich applications needing higher memory and advanced analog/USB-C integration.
